Non-English texts in Stripe possible? - localization

Question

Successfully integrating Stripe into my online shop, I completely failed to get information on whether/how to configure Stripe to return error messages in German instead of English.
So my question is:
Is there a way to have localized error messages when using the client-side API "https://js.stripe.com/v2"?
Update 2014-05-03
I've asked the same question on Twitter and one of their staff (I guess) told me that this is currently not possible and on their TODO list.

Answer 1

For further reference:
While you can't use human messages on stripe errors to be displayed directly on localized pages, you can take advantage of response.error.code to provide your own translations.
var errorMessages = {
incorrect_number: "The card number is incorrect.",
invalid_number: "The card number is not a valid credit card number.",
invalid_expiry_month: "The card's expiration month is invalid.",
invalid_expiry_year: "The card's expiration year is invalid.",
invalid_cvc: "The card's security code is invalid.",
expired_card: "The card has expired.",
incorrect_cvc: "The card's security code is incorrect.",
incorrect_zip: "The card's zip code failed validation.",
card_declined: "The card was declined.",
missing: "There is no card on a customer that is being charged.",
processing_error: "An error occurred while processing the card.",
rate_limit: "An error occurred due to requests hitting the API too quickly. Please let us know if you're consistently running into this error."
};
function stripeHandler( status, response ){
if ( response.error && response.error.type == 'card_error' ){
$( '.errors' ).text( errorMessages[ response.error.code ] );
}
else {
// do other stuff (and handle api/request errors)
}
}
The list of codes is documented here (currently, right column, in the "codes" section).

Answer 2

NOTE
The text is not production ready. It's just the developer text.
Some errors shouldn't be showed to the user. If I have some better texts I will re edit this. If someone has the time to do so, feel free to edit.
If you would like to provide their english text:

Currently, when initializing Stripe you can pass the locale parameter
I could give more details, but it would be too much, the documentation says it all:
A locale used to globally configure localization in Stripe. Setting the locale here will localize error strings for all Stripe.js methods. It will also configure the locale for Elements and Checkout. Default is auto (Stripe detects the locale of the browser). Note that Checkout supports a slightly different set of locales than Stripe.js.
